IEEE 802.3bz: New Ethernet Standard Brings 5 Times Faster Internet Over Existing Cables

ieee-standard-5gbps
 A new Ethernet standard IEEE 802.3bz has been released which boosts the theoretical bandwidth over the existing twisted pair copper wires to 2.5Gbps (2.5GBASE-T) and 5Gbps (5GBASE-T). That’s five times the current theoretical bandwidth achieved on cables designed according to the 1000BASE-T standard.
The Ethernet Alliance has released a new set of specifications for the copper wire cables, 80.23bz. The new Ethernet specification puts forward two new standards 2.5GBASE-T and 5GBASE-T. Up until now, our wired networks have been confined to 1Gbps speed cap as per the widely implemented 1000BASE-T (IEEE 802.3ab). Now, the theoretical speeds are going to make a significant leap.
The 802.3bz specification has boosted the speeds to 2.5Gbps and 5Gbps up to 100m length on the same Cat5e and Cat6 copper wires currently used. The perks are only in case of the wires. Large organizations having thousands of meters of copper cabling inside their offices could take a breath of relief because they won’t have to reinstall them. Although, device hardware will have to be upgraded to support the new IEEE 802.3bz specification.
“Going beyond 1 Gb/s with existing Cat5e and Cat6 cables was little more than a talking point two years ago. But now with NBASE-T, we have the ability to extend the life of an enormous asset —your wired network. The Cat5e and Cat6 installed in just the last 15 years now exceeds an estimated 70 billion meters of cabling, which is more than 10 trips to Pluto,” said Sachin Gupta who is the VP of Product Management at IEEE.
We have already achieved 10Gbps theoretical bandwidth but its high equipment cost is a downside and contributes to its low adoption rate. The new 802.3bz standard might come up with cost effective network products which can benefit both home and office users.
It won’t improve the speed of your internet as it depends on the speed provided by your ISP which currently maxes out at 1Gbps. Maybe in future ISPs offer higher speeds. You will see the effect during multiplayer gaming session and file sharing over your home network. The standard is recently released and it might be a couple of years till we have products based on it.
